    In reverse biasing

    A)  Large amount of current flows

    B)  Potential barrier across junction increases

    C)  Depletion layer resistance decreases

    D)  No current flows

    Correct Answer: B

    Solution :

    [b] In the reverse biasing of p-n junction, the voltage applied supports the barrier voltage across junction, which increases the width of depletion layer and hence increases its resistance
